Study on Influence of Construction Environment on Parameters of Reinforcement and Pile Foundation Test Results

为了研究施工环境对钢筋计参数及桩基试验结果的影响,通过理论分析与现场堆载试验相结合的方法,根据力学平衡条件现场重新标定钢筋计,并得出了钢筋计修正系数K值的计算公式.纠正了钢筋计测试的计算误区,从而准确地计算出桩身不同深度处各截面的轴力.研究结果为试验数据的准确性提供了可靠的保障,为钢筋计在桥梁桩基受力分析研究提供了标定方法.

In order to study the influence of construction environment on the parameters of steel bars and the re- suits of pile foundation test, through the combination of theoretical analysis and field loading test, according to the mechanical balance conditions on-site re-calibration of steel, the formula of calculating the K value of the correction coefficient of the steel bar is obtained, the calculation errors of the steel bar test is Corrected, which helps to accurately calculate the axial force of the pile at different depths of the cross section. The results of this study provide a reliable guarantee for the accuracy of the test data, and provide a calibration method for the rein- forcement analysis of the bridge pile.
